Yep, you should have no problems with that. My temp floats between 77-80 and my xenia is growing like crazy. I had a/c problems about 2 weeks ago and they stayed open up til around 83-84 degrees. It peaked at 85 and they looked real bad for about 3 hours.
BTW: If your a/c goes out, check your breaker box first. A circuit blew and I got a free sauna for 4 hours or so... I felt stupid when the ac guy found the cause of the problem.
